Abstract
An articulated mechanism and associated systems and methods therefore are disclosed. An example articulating mechanism within the scope of the disclosure includes a stud, a keyed washer having a plurality of threaded apertures, and a nut. The nut threadingly engages the stud. The nut includes a plurality of apertures segregated into a plurality of groups. A size of the apertures formed in the nut are larger than a size of the apertures formed in the keyed washer, resulting in an angular variation over which an aperture of the nut remains aligned with an aperture of the keyed washer. The apertures of the respective nut and washer are arranged such that at least one aperture of the nut aligns with an aperture of the keyed washer continuously throughout rotation of the nut relative to the keyed washer. The aligned apertures receive a fastener to secure the nut to the keyed washer.
